The attack against Joe O'Dea, the GOP's Senate nominee in Colorado, by the former President is angering Republicans and leaving them wondering if he cares about the party winning back the majority.

The Democrats spent $4 million against O'Dea in the primary and he was already in a tough fight against Bennet.

Republicans are worried that any chance he has of pulling off an upset is gone because of Trump.

Cramer told The Hill that it was not helpful. I don't want O'Dea to lose because Donald Trump urged Republicans not to vote and we came up short of the majority.

If he was a senator. Cramer said that they wouldn't stand a chance if McConnell opposed every Republican nominee who criticized him. The nation needs to be more important than personal crimes.

Trump labeled O'Dea a "RINO", or Republican in name only, and said that "MAGA doesn't Vote for stupid people with big mouths."

The barb came after O'Dea said that he would campaign against the former president if he were to run again.

The remarks came at a bad time for O'Dea as ballots were to be distributed in the state.

A GOP strategist involved in Senate contests likened Trump's attack on O'Dea to his rhetoric surrounding the Georgia runoffs after his election loss in 2020.

If O'Dea is the difference between a GOP majority and minority, you think about the policy ramifications. A second GOP operative involved in Senate races said that to think you can be anywhere right of center and be willing to mortgage on a Republican majority just because someone says not nice things about you is revealing.

In Colorado two years ago, President Biden defeated Trump by 14 points, and it was all about fealty to him.

While O'Dea is one of the GOP's best Senate recruits this cycle, he still faces a steep climb to defeat Bennet, a two-term incumbent. In Colorado, no Republican has won a statewide general election in the last four years.

You need everyone to vote for you if you want to win Colorado. The second GOP strategist said that any kind of shooting inside the tent could have profound consequences. Everyone you need.

O'Dea said in a statement that he is a construction guy and not a politician.

President Trump is entitled to his opinion, but I'm my own man and I'll call it like I see it. O'Dea said, "Another Biden, Trump election will tear this country apart"

O'Dea said that the elections should be focused on Joe Biden's failures and not on the 2020 election. The country needs to move forward.

Bennet had a 6 percentage point lead over O'Dea according to the survey.

The Senate Leadership Fund, a group run by top allies of McConnell, gave a million dollars to an O'Dea super PAC. The group is keeping an eye on the race and is not ruling out making more investment.

Some Republicans are not sure if Trump's comments will make a difference when all is said and done. O'Dea has been vocal about his opposition to the former president and they think the state's antipathy for Trump will make his comments null and void.

O'Dea has clearly stated that he is a Republican. He is a business person One Republican with Trump ties said that he had been clear about what he thought about Trump. It won't change things for O'Dea either. It isn't a big deal. It gets some attention from the president. It will get O'Dea the same. O'Dea isn't a fan of Trump. O'Dea is bashed by Donald Trump. O'Dea has the ability to say'see?'.

The Monday statement was probably due to Trump's continued push to install loyalists throughout the GOP ranks, as well as the state party and county level.

The strategist said that Trump wanted the party to reflect his personality.
