President Donald Trump’s midterm roadshow to rally the GOP is stopping in swing-state Arizona and a Republican-leaning U.S. House district in Montana. Trump will be rallying support in Bullhead City, Arizona,  on Wednesday for Rep. Andy Biggs, who seeks the governorship. Trump later is set to travel to Western Montana’s 1st District to try to boost Aaron Flint. The trip comes as Republicans are retreating from a handful of battleground U.S. House races, while Democrats are racing to raise money to boost candidates who seemed like long shots earlier this year. The strategy points to an increasingly defensive posture by Republicans and new aggression from Democrats.
