Whether Mitt Romney can go from being a candidate for president to one for U.S. Senate. And even whether Okies can start toking. Battles will also be settled between the establishment and activist wings of the Republican and Democratic parties as voters head to the polls for primaries in Colorado Maryland New York Oklahoma and Utah and for runoff elections in South Carolina.

Mike Coffmans seat in the 6th District in which Hillary Clinton beat Trump by nearly 9 percentage points in 2016 is high on the Democrats target list. But before they can take him on they have to pick a challenger and that battle has gotten so heated it overflowed from Colorado into Washington. Levi Tillemann an inventor and former Energy Department adviser supported by the progressive group Our Revolution sparked a mini-rebellion against Democratic leaders in the House when he released a secret recording in which House Democratic Whip Steny Hoyer of Maryland urged him to drop out of the race.
