Which Republican Senate candidate is most likely to win Colorado’s election?

The Denver Post is reporting that Sen. Cory Gardner is poised to win the GOP nomination for Colorado’s Senate seat on Tuesday.

Gardner, who is also the governor of Colorado, was the top Republican choice for President Donald Trump’s 2016 campaign, but he dropped out after the GOP nominee lost in Colorado.

However, he is now looking to take advantage of a newly expanded primary voting system that allows voters to choose between multiple candidates in the race to fill the seat Gardner vacated in 2018.

Gardner announced his campaign in February, saying he would run if he won the primary.

The Post’s report indicates that Gardner will not be the only Republican to win on Tuesday: Sen. Mark Udall (D-CO), a former presidential candidate, will be running against Rep. Mike Coffman (R-CO).

The Colorado Independent, a conservative paper, also reported the potential winner will be former President Barack Obama.

The paper reported that Coffman has been a strong opponent of the Iran nuclear deal, and that Udall “has long been opposed to it.”

Udall has also made a number of high-profile statements against Trump.
