When Reagan left office, the unemployment rate was 5.4%. It was 7.3% at the end of his first term, falling from a peak of 10.8%. (Back then, the methodology used to calculate unemployment included more people than the current version of U3.)
It's highly doubtful that Obama's policies will cause a 3.5 point drop in unemployment by the end of his first term - unless, of course, millions more long term unemployed drop out of the labor force altogether.
Another way to look at this is, at the beginning of Reagan's terms, there were 100M Employed in the U.S. When he left office, this figure stood at 116.7M. A net increase of 16.7M jobs were created during his eight years in office.
When Obama was inaugurated, 142M people were employed; that amount decreased by 3M by the end of March 2010 when 139M were employed. Over the equivalent amount of time during Reagan's first term, the number employed was slightly down (a net decrease of <300K).
Obama's policies are worsening the situation. Reagan's stabilized it, and then established an environment conducive to economic growth and job creation. Note how Obama's team is even now talking down expectations for job recovery and spreading a meme that it will take a long time for unemployment to be significantly reduced.
