Look, at primary time you can't even get Republicans out to vote for Republicans, they sure as hell won't be coming out in droves to vote for Democrats, even ones they detest.

An example from last week's primaries in Iowa:
GOVERNOR - REPUBLICAN PARTY
Vote for 1 Precincts Reported 1871/1873
TERRY E. BRANSTAD Republican Party 114197 50.33%
ROD ROBERTS Republican Party 19849 8.75%
BOB VANDER PLAATS Republican Party 92742 40.88%
WRITE-IN Republican Party 96 0.04%
Total Republican Voters: 226,884
The current Dem governor was unopposed, so let's compare the above to the Democrat Senate Primary:
U.S. SENATOR - DEMOCRATIC PARTY
Vote for 1 Precincts Reported 1871/1873
ROXANNE CONLIN Democratic Party 52637 77.47%
THOMAS L. FIEGEN Democratic Party 6446 9.49%
BOB KRAUSE Democratic Party 8719 12.83%
WRITE-IN Democratic Party 141 0.21%
Total Democrat Voters: 67,943
