Post-Announcement Bounces.

Using the realclearpolitics polling average, I'm making a list of the candidates' national polling on the day of their announcement and exactly three weeks later. I think one month is too long, and two weeks might not contain enough polls to make a good measure of a bounce.

Ted Cruz
March 23: 4.6%
April 13: 10.5%
+5.9%

Rand Paul
April 7: 9.2%
April 28: 9.4%
+0.2%

Marco Rubio
April 13: 7.3%
May 4: 14.3%
+7.0%

Ben Carson
May 4: 5.0%
May 25: 7.8
+2.8%

Carly Fiorina
May 4: 1.0%
May 25: 1.3%
+0.3%

Mike Huckabee
May 5: 7.5%
May 26: 8.6%
+1.1%

Graham, Walker, and Santorum won't get a bounce.

I added the Carson, Fiorina, and Huckabee bounces or lack thereof.

I wonder what kind of bump Bernie will receive now that he has kicked off his campaign.
