13 high-profile Republicans have officially entered the campaign for the party's 2016 nomination. Only three major prospects remain: Ohio's Kasich, Wisconsin's Walker and New Jersey's Christie, each planning to announce his intentions in the coming weeks.
They are expected to join a field with five sitting or former senators, five current or former governors, two business leaders and a retired neurosurgeon. The "in or out" phase of the Republican presidential race is nearing its end, but with just over seven months until Iowa's leadoff caucuses, no clear leader has emerged in the race for the nomination.
There's so many candidates, it's almost impossible for the average person to keep track," said tea party leader Mark Meckler, who heads up the conservative group Citizens for Self-Governance.
