In the 2008 GE, I know of a friend who is an Umno member,who together with his group of friends who are also Umno members did not vote and boycotted the GE. After Pak Lah was removed as PM by the Umno supreme council and appointed Najib as Umno president, this group of Umno Malays voters have returned and support the party.
As for malays who are not Umno members but who voted for the opposition in the last GE. Currently Umno have not reach out to them. I recently spoke to a Bumiputera businessman friend and he told me that Umno have not reach out to him and his friends. Under the circumstances,it will be difficult for him and his friends to vote for BN in the next GE.So far they have been in business,Umno did not offer any assisitance and have not reach out to them.
From the above,it can be confirmed that Umno have not recover the entire Malay ground it lost in the last GE. On the other hand,it have only recovered the votes of its members who did not come out to vote. A good indication of the level of support of the malays for UmnO and BN will be the by election for the state seat of PORT KELANG which will be held in March 2011.
