Donald Trump’s net approval has slumped to its lowest this term as the United States government shutdown breaks the record for the longest shutdown. Democrats had big wins in state elections on Tuesday.

I previously covered the ongoing US government shutdown on October 9, eight days into a shutdown that began on October 1. This shutdown has now lasted 38 days, beating the previous record 35-day shutdown that was set during Trump’s first term.

Although Republicans hold the presidency and majorities in both chambers of Congress, they cannot pass a budget without Democratic support in the Senate owing to the Senate’s requirement for 60 votes out of 100 senators to invoke “cloture” and end a “filibuster”.

Republicans hold a 53–47 majority over Democrats in the Senate, so they need seven Democrats to vote with them to obtain cloture. Democrats are refusing to help to pass a budget unless health insurance subsidies are extended.

For the first three weeks of the shutdown, Trump’s ratings were resilient, with his net approval in analyst Nate Silver’s aggregate of national polls rising slightly to -7.5 on October 19.

But since then, Trump’s net approval has slumped 5.5 points to -13.0, a low for him this term. Currently, 55.1% disapprove of Trump’s performance while 42.1% approve.

Trump’s net approval on the four issues tracked by Silver have all fallen recently. He now has a net approval of -4.9 on immigration, -17.6 on the economy, -17.8 on trade and -28.9 on inflation.

In Silver’s historical comparison on how Trump’s ratings compare with previous presidents since Harry Truman at this point in their presidencies, Trump’s net approval is only better than during his own first term. Joe Biden’s net approval was -8.3 at this point, making him the next worst on net approval.

Since a peak for the US benchmark S&P 500 stock market index on October 29, it has lost 2.5%. But in the last six months, it has gained nearly 20%.

Trump’s ratings will probably rebound if the shutdown ends soon. Unless something goes badly wrong with the US economy or the stock market, his ratings will probably return to net high single-digit negative, not net double-digit negative.

Democrats had big wins at state elections

US state elections occurred on Tuesday in New Jersey and Virginia. Democrats won the Virginia governorship by 57.2–42.6 over Republicans, a gain for Democrats. They also won the other two statewide races for lieutenant-governor and attorney-general.

Democrats won the lower house of the Virginia legislature by 64–36, a 13-seat gain for Democrats. The upper house was not up for election, but Democrats hold a 21–19 majority there. At the 2024 presidential election, Kamala Harris defeated Trump in Virginia by 5.8 points, though Trump won the overall popular vote by 1.5 points.

Democrats held the New Jersey governorship, winning by 56.4–43.0, far exceeding polls that gave Democrats a low single-digit lead. They lead in the lower house by 53–19, with eight seats uncalled.

If the uncalled seats go to current leaders, Democrats will win by 57–23, a five-seat gain. Democrats hold the upper house by 25–15, which was not up for election. Harris beat Trump in New Jersey in 2024 by 5.9 points.

In June, democratic socialist Zohran Mamdani had won the New York City Democratic mayoral nomination, defeating former New York governor Andrew Cuomo by 56.4–43.6 after preferences to win the Democratic primary. On Tuesday, Mamdani defeated Cuomo, who ran as an independent, in the general election
by 50.4–41.6, with 7.1% for a Republican.

Unlike the primary, the general election used first past the post. But preferences would not have changed the outcome as Mamdani exceeded 50%.

In response to Texas Republicans gerrymandering Texas to create five additional federal Republican seats, California Democrats proposed retaliatory gerrymandering of California’s federal seats. A referendum was needed to approve this gerrymander. With 79% reporting, “yes” to gerrymandering had won by 63.9–36.1. Harris won California in 2024 by 20.1 points.

Implications for the 2026 midterm elections

At November 2026 midterm elections, all of the House of Representatives and one-third of the Senate will be up for election. In Virginia and New Jersey’s gubernatorial elections, there were respectively 8.8 and 7.5 point swings to Democrats from the 2024 presidential margin in those states.

If these swings are applied to Trump’s national margin of 1.5 points in 2024, Democrats would win nationally by 6.0 points (New Jersey swing) or 7.3 (Virginia swing). So if the swing in either state occurs nationally in 2026, Democrats are very likely to gain control of the House.

There will be 35 seats up for election in the Senate next November (33 regular and two special elections). Republicans hold 22 and Democrats 13, but only two Republican seats are thought vulnerable: Maine and North Carolina.

In 2024, Harris won Maine by 6.9 points and Trump only won North Carolina by 2.2 points. Trump won all other states Republicans are defending by at least a double-digit margin. Even if the swing in Virginia happened nationally, Democrats would gain only two seats and Republicans would hold the Senate by 51–49.

It’s become increasingly difficult for Democrats to win the Senate, as the two senators per state rule skews Senate elections towards low-population, rural states.

In the Fiftyplusone generic ballot average, Democrats lead Republicans by 45.0–41.9. The low single-digit lead for Democrats hasn’t changed since April. The current 3.1-point Democrat lead is below what happens from applying the swing in New Jersey and Virginia nationally.

While Trump’s ratings have dropped, there hasn’t been a Democratic surge on the generic ballot. That suggests voters are blaming both parties for the shutdown.
