I don't think that the majority should automatically get to carry out their agenda. If 50.1% of people voted in representatives, those representatives should not get to make dictatorial changes that affect the 49.9% of people who voted against them. There needs to be compromise. However, the GOP has decided in recent years that they will not compromise under any circumstances and it's caused a huge governing problem. More than a third of all filibusters done in US history were done by the GOP in Obama's first 6 years for example. I agree we can't have the government do nothing like that, but we certainly also can't allow the majority to be tyrannical.
Assuming Hillary is elected and people like McCain do stonewall nominees like he claimed and like the GOP is doing now to Garland, I'd support the President issuing warrants to force Congress to do it's fucking job. Honestly, there's 47 Senators who could legitimately be charged with treason already.
