Republican Ted Cruz recently explained that the reason his Senate colleague John McCain has been questioning his eligibility for the White House is to help boost Marco Rubio’s run for president. But unfortunately for Mr. McCain, Senator Rubio’s nothing more than a smooth-talking version of Governor Scott Walker. And just like Mr. Walker, Mr. Rubio believes he can cozy up to establishment insiders, yet come across as an independent, conservative outsider. Ultimately, Mr. Walker’s candidacy for president failed miserably because he tried to make everybody happy. And it’s just a matter of time before Marco Rubio’s campaign also becomes a piece of Wisconsin Swiss cheese.
