Buttigieg is already seeing a strong bounce in New Hampshire thanks to how he did in Iowa. By beating his Iowa polls by nearly 10 points (taking into account undecideds), Buttigieg would be expected to do seven points better in New Hampshire than his pre-Iowa New Hampshire polling average would indicate. Buttigieg probably needs an even bigger bounce coming out of New Hampshire than he got coming out of Iowa. By outperforming expectations in Iowa, Buttigieg probably helped himself out in these places. Of course, we don't even know yet if Buttigieg officially won Iowa.
