Ah, yes. Another brilliant 2smart analysis. An already unpopular governor loses an election to an (initially) very popular challenger, and doofus decides that it's a rejection of Barack Obama and Democrats in general. Never mind that the challenger's initially overwhelming lead in the polls dwindled considerably as the election grew nearer. Never mind that poll numbers for the incumbent continued to improve when Obama stumped for him. Never mind that exit polling show Obama with a 57% approval among NJ voters in today's election, despite having elected the Republican candidate. Never mind that exit polls show that the top issues that voters were concerned about were the economy and property taxes.
No, 2smart, the clear message is that this race was won on issues of immediate concern to residents of NJ, and on their opinions of the candidates who were actually running in the race. Your claim that it was a referendum on Obama and the national Democratic party is not in evidence, no matter how dear that fantasy is to you.
