However, Chen alienated moderate constituents who supported the status quo and those with cross-strait economic ties, as well as creating tension with the mainland and disagreements with the United States. In 2008, referendums were held on the same day as the presidential election asking whether Taiwan should join the UN under "Taiwan" (DPP's motion) or "Republic of China"/any other suitable name (KMT's motion). Both failed because only 35 percent of the electorate, below the required threshold of 50 percent, voted. The Chen administration was also dogged by public concerns over reduced economic growth, legislative gridlock due to a pan-blue, opposition-controlled Legislative Yuan, and corruption investigations involving the First Family as well as government officials, lowering the President's ratings to the 20s near the end of his second term.
