Voters in six states went to the polls Tuesday in primary elections that underscored deep divisions within both major parties ahead of the November midterms.
The Democratic primary for governor in Wisconsin emerged as the key test of a national battle between the party's progressive and moderate wings. Reports differed on the outcome: one said a moderate had clinched the nomination, while another said the race remained neck and neck early Wednesday and was largely unsettled.
Elsewhere, results from the six states highlighted ongoing conflicts inside both parties, as candidates aligned with different factions competed for their parties' nominations. The outcomes set the stage for intraparty tensions heading into the general election.
