On what grounds does the US Senate have any say on a state election or on this case?None that I know of, but I'm not no fancy pants lawyer neither. The Constitution leaves the election of senators up to the States. I don't see anything giving them the authority to override state law. I think they're blowing smoke.
Please see reply 25. The body (House or Senate) is the final arbiter of all races per the Constitution, and the Democrats have always used that to their advantage. Trust me, they will seat Al Franken regardless of the outcome of the recount. And the writer is mistaken about the anticipated results. When the Democrats control a house, contested races are ALWAYS decided in favor of the Democrat regardless of the circumstances. Ron Paul in his second run for Congress was the victim of massive and obvious voter fraud (he should have won hands down) but his Democrat opponent was seated anyway. Don't bother the Democrats with facts or analysis, the Democrat will get seated. And the stupid electorate will forget in two years and vote for the morally bankrupt, corrupt, lying, thieving Democrats.
Remember, to a Democrat, something is "fair" only when the Democrat wins.
