This is the most important week of President Obama’s bid for a second term in November.

Consider:

●The Supreme Court will rule not only on the constitutionality of Obama’s landmark health-care law, but the highest court in the country also will hand down judgment on Arizona’s stringent illegal immigration law.

●Congress will be forced into action (or inaction) on federal student loans and highway projects — both of which will expire within the next week.

●The House will vote on whether to hold Attorney General Eric Holder in contempt of Congress due to his refusal to turn over some documents related to the “Fast and Furious” gunrunning operation.
