President Donald Trump — making a tremendous commitment to the Republican candidates running across the country in a variety of races in these all-important 2018 midterm elections — holds a rally in Belgrade, Montana, today.

It is his fourth appearance in the state on behalf of GOP candidates this fall.

Montana voters will get to choose between incumbent Sen. Jon Tester (D-Mont.) and his GOP challenger Matt Rosendale in just a few days — with the race remaining a toss-up.

Tester has fought hard to keep control of his seat for another six-year term as Election Day approaches.

Meanwhile, Republicans have put a lot of attention on the race in the hopes the seat will flip on November 6.

Both sides have received millions of dollars from outside groups and support from major political figures.

Senate Republicans see the race as critical to their chances of maintaining or even improving their narrow 51-49 majority.
