With Gingrich planning to withdraw from the race, I did an update to my post about a horary from last December asking whether he would get the nomination. The original post is at

Addendum: I wanted to add that in a comment in March 2012 on this blog Ashish Kaushal, using Jyotish techniques, predicted that Romney would have clear sailing to the Republican nomination after May 1st, which is the day Gingrich plays with officially withdraw from the race. Here is his comment:
Ashish Kaushal says:
“Good interpretation. What do you think his chances are for grabbing the primaries. At this point he is the prime contender but there is valid threat from Rick Santorum. Will it change in near future? Per my Jyotish calculation he should be only valid contender after May 1st. He should sweep almost all the primaries after May 1st. If this happens only than he will be able to present a real competition to Obama. Otherwise he is just able to win primaries then there will be no good chances in Nov 2012.”
Very impressive, Ashish!

Using Vedic Astrology, I did predict that Newt will give up during 1st week of April. But, he did it after 3 weeks of my predicted date.
Here is my prediction details: http://myastrologypredictions.wordpress.com/
Thanks for the Vedic perspective. Gingrich withdrew on May 2, less than 24 hours before transiting Uranus crossed the IC of the horary chart.
