A crowded Republican presidential contest had pundits raising the specter of a brokered Republican National Convention as early as last fall, but after the Iowa caucuses, it looks like Democrats will be the ones slogging through a long primary fight, Guggenheim Partners' Chris Krueger said Tuesday
But The Associated Press called the contest a virtual tie. With all precincts reporting, Clinton led Sanders by less than three-tenths of 1 percent, it said.
"I think the moral victory of the Sanders campaign against Hillary is going to have a bigger impact in terms of the length of the Democratic race," Krueger told CNBC's "Squawk on the Street."
That's because unlike Republicans, Democrats don't hold any winner-take-all primaries, which award all of a state's candidates to a single victor, he said.
Despite Sen. Ted Cruz's victory in Iowa, Krueger said, the Republican race could come to a screeching halt on March 15 if Florida Sen. Marco Rubio prevails in winner-take-all contests in Ohio and in his home state, Krueger said that looks increasingly likely after Rubio turned in a surprisingly strong third place finish just behind No. 2 outsider Donald Trump.
