Elon Musk is now the biggest donor in this year's midterm elections.

He gave more than $276 million since July.

He wants to help Republican majorities in Congress.

The New York Times reported the numbers first.

Andrew Romeo confirmed them.

He is a spokesperson for Musk's super PAC.

The money includes $158 million to the Senate Leadership Fund.

This group supports Republican Senate candidates.

The Times called it one of the largest political donations in American history.

Another $76 million went to America PAC.

This is Musk's own super PAC.

It has built a big turnout operation.

Musk also gave $10 million to Lone Star Liberty PAC.

This group supports Ken Paxton.

He is the Republican Senate nominee in Texas.

This is a big change.

Last May, Musk said he wanted to cut back on political spending.

He said he had done enough.

He has also kept a lower profile than in 2024.

In 2024, he appeared on stage with Trump at rallies.

He later had a falling out with Trump.

But the two have since reconciled.

Trump gave him the National Medal of Science last week.

Republicans now have a large money advantage over Democrats.

That is a rare bright spot for the party.

The party is bracing for possible losses.

Voters are frustrated about the president's performance.

They are also upset about high prices.

And they are upset about the unpopular war with Iran.

Romeo said the investments let the GOP "get its message out."

He said they give Republicans a chance to defy history.

Democrats accused Republicans of trying to buy the elections.

Lauren French is with the Democrats' Senate Majority PAC.

She said they are spending tens of millions.

She said they want to outrun their unpopular candidates, president and economy.
