With the Nevada Caucus this Saturday, Mitt Romney currently leads there by 20 points according to new Las Vegas Review-Journal poll.

Mitt Romney 45%
Newt Gingrich 25%
Rick Santorum 11%
Ron Paul 9%
Noe of these/don’t know 10%

The first night of polling by PPP also found Romney with huge double digit lead over the rest of the field, according to the results Tom Jensen shared with Jon Ralston.

The first night impressions via pollster Tom Jensen:

“Romney leads Newt by about 15-20 points. The main suspense may be whether he gets over 50%, he will certainly have a chance. Paul is 3rd and Santorum 4th, both around 15%. The chances of Paul besting Gingrich for 3rd are pretty minuscule.

Given the very large Mormon population in Nevada and the fact that Romney won the state in 2008, it is not surprising that Romney is doing very well this time around. Still a win is a win. If Romney wins Saturday he will be 3 for 5 in primaries. It will get Romney delegates, and more importantly help cement the impression that Romney is becoming inevitable.

It is going to be tough for Gingrich or Santorum to build momentum for another surge this month with there being only one debate and Romney steadily collecting wins.
