Maybe so....but Romney easily carried IN and MO so the GOP US Senate candidates in those states must have been exceptionally weak.
if you bothered watching the main debate between Lugar and the new guy back in the primaries you'd found they were not far apart at all on any issues ~ still, you'd had to agreed that Lugar was a drooler. I am pretty sure he'd lost this time too.
Vance Hartke once won the race for Senate while Republicans won every other office on the ticket.
That's how evenly divided Indiana elections can be.
In Missouri neither of the TEA Party backed Conservative candidates won the primary. Instead, the fellow the Democrats ran campaign advertising for won.
Rence Preibus, faced with a dilemma ~ to support a Conservative, or give up the race, gave up the race.
I don't think Consevatism was the problem, but we are not yet rid of Rence ~ and he's long overdue or a departure from party affairs.
