Jeb Bush is entering a critical phase of his Republican presidential campaign, with top donors warning that the former Florida governor needs to
demonstrate growth in the
polls over the
next month or face serious defections among supporters.

poll ratings on the back of election successes like Rotherham, Eastleigh and local elections and the ensuing publicity and then flattening out again until the
next opportunity to
demonstrate their support comes along.
