Yet the accusations against Villar are so wide-ranging that it’s probably best, for space reasons, to focus on only the most recent— his involvement in reportedly corrupt infrastructure projects.

According to Philippine Daily Inquirer columnist Solita C. Monsod, who is also a respected economics professor, there are ‘incontrovertible facts’ in Senate Report 780 demonstrating Villar's controversial involvement in at least three public works projects: 1) the Manila Cavite Toll Expressway Project (MCTEP); 2) the original C-5 extension project linking the South Luzon Expressway (SLEX) with the Coastal Road; 3) the Department of Public Works C-5 extension project (CX5), which , together with the Las Pinas-Paranaque Link Project (LPPLP), also links SLEX to the Coastal Road.

It’s alleged that problems revolving around Villar's involvement in the CX-5 and LPPLP project centre on his having apparently used funds from his Senate ‘pork-barrel’ allocation for the CX-5 project, which also &paved the way for the funding of the LPPLP.’ On paper, this looks fine. Except that Villar is reported to own about 50 hectares of land in the vicinity of these projects, and so stood to profit enormously from construction.

Monsod goes on to say that the Villar and related properties were bought by the government for 168.1 million Pesos, whereas the non-Villar properties were bought for only 22 million Pesos—a significant difference. And this is by no means all—there’s considerably more documentation showing suggesting corruption and conflicts of interest, too much to list here.

So, it has so far been left to Aquino to be the standard bearer for honesty and integrity. But there have also been attempts to link him to a dubious construction project, and as the frontrunner in recent polls it’s perhaps inevitable there’ll be mud slung his way.

Teodoro, Aquino's second cousin, has so far managed to avoid being personally tainted with suggestions of corruption, and has been praised for being a smart, efficient administrator. However, being the official candidate of the party in power makes him vulnerable by association to real or imagined corruption allegations against Arroyo, her family and supporters. And there’s plenty to be associated with—the controversial NBN-ZTE deal with a Chinese firm, the Bolante case and the ‘Hello, Garci’ scandal in which a tape recording was released with Arroyo apparently discussing with the then election commissioner the rigging of the 2004 national election. This downside to being associated with the ruling coalition is reflected in Teodoro generally polling last among the major candidates.

As a result of this, rather dispiritingly, many pundits believe this election will be about choosing the lesser of all evils. Even more dispiritingly, though, is the fact that it wouldn't be much of a surprise given the nature of Philippine politics if the most corrupt candidate emerges victorious.
